Excellent Free and Open Source JavaScript Frameworks

10 Useful Free and Open Source JavaScript Frameworks

JavaScript is an extremely popular prototype-based scripting language that is one of the core technologies of the World Wide Web. It provides for enhanced user interfaces and dynamic websites. JavaScript can, for example, check information entered into a form to ensure it conforms to what is expected by a database.

JavaScript should not be confused with Java. While both are used to write computer software that can run inside a web browser, they are unrelated programming languages; Java offers a lot more than a programming language.

There is a wide range of open source JavaScript frameworks that are available to help speed up the development process of websites. The purpose of this article is to help newcomers to JavaScript narrow the field to a manageable number to explore. The frameworks offer a wide range of features, such as Document Object Model querying and manipulation, Asynchronous JavaScript and XML (Ajax) request handling, and an interface widget library being a few examples.

To provide an insight into the quality of software that is available, we have compiled a list of excellent JavaScript frameworks. All of the software featured here is released under a freely distributable license.

We’ve not included Node.js, jQuery, React, Backbone.js, Knockout, and others in this roundup. They are probably best described as JavaScript libraries rather than frameworks, but that depends on the definition of the two terms. For example, sometimes the difference between a library and a framework is … “a library is when you call some code, a framework is when your code is called from somewhere”. But while they may not be fully fledged frameworks, the distinction is often blurred.
